It's just a pack of effects for anyone who is looking for pre made explosions, flames, among some extras. It may suit the art/animation style the client is looking for and works as a faster alternative. It's also pretty cheap :P

these kinds of animations are needed in so many games and would normally either look crappy or cost time/money to have an artist make em right.. if i was workin on any small project that needed any of these effects id buy the pack!

maybe you should try selling them on other places too.. im sure there are alot better places than fgl to sell art assets
